So after the story you don’t really get anymore interactions with the Orders in GW2. Durmand Priory, Order of Whispers, and the Vigil don’t really have any relevance after the story is done and I was thinking maybe there should be random optional missions in the game. The Priory would be focused on recovering artifacts as some of their missions, the order would focus on eliminating targets, and the vigil would deal with keeping the peace and killing monsters.
Maybe only be able to do one mission a day ( Daily missions ), and it would be a good place to put more boss fights and maybe some raid type missions to accommodate for players wanting those types of things. Maybe add rank levels for the Order your in and exclusive awards and armors.
the Pact could also have the same things but add much harder content for more experienced players. 3 teams of 5 players with one player from each order leading the their respective teams, maybe 3 different objectives at the same time and other team oriented ideas.
